I would go with my gut. As a parent, it’s my job to help the kids figure things out but ultimately it’s their life. Attending a school that you feel is not a good fit is a red flag. There are lots of options ( a few were mentioned), what are the other schools you got into? Is there a chance you could still go there? What about taking just a semester off? What about going somewhere with rolling admissions then transferring out? What about doing a year abroad as a Freshman ( this may be the best bet if you plan to transfer anyway).
If you decide on just going for a year and then transferring it could be rough. You will have to do well academically. If the school/people bother you that’s going to be hard. Prestige isn’t relevant if you aren’t happy. And it is only prestigious to someone who also thinks its a good school. If you don’t like it for whatever reason you don’t like it. I am gathering from your post that perhaps the folks there aren’t people you would normally relate to. The Summer program is a taste so real students may be slightly different. I know nothing about the school but even I know that it has a particular reputation for being extreme in a single direction.
Since you are obviously a strong student I would really not suggest CC at this point. Knowing your major would help. Perhaps there is a great small college that would love to have you!! They might also be more open to someone who had a change of heart. Also, consider transferring after one semester. It would be something like, I tried it, I didn’t like it and now I know what I want. Unfortunately, if you are FA you have to consider transfers get almost zero FA so be careful there.
